OSPF on-demand configuration was designed for efficient operation over on-demand circuits like ISDN, X.25 switched virtual circuits (SVCs), and dialup lines. Since these are billed on usage basis, you don't want your OSPF protocol to keep these circuits up 24-7. This feature allows OSPF to suppress periodic hellos and the periodic refreshes of LSAs are not [...]]]></description>

I was working through IEWB Vol Lab 4 and ran across this summarization task for IPv6. I can do summarization when it comes to IPv4 but I was kind of sketchy on IPv6 summarization. Well I attempted the task and was close to say the least. So after I went through the whole task and [...]]]></description>

Technically I was suppose to start OSPF yesterday but I started working on it over the weekend. I already went through Narbik's soup-to-nuts labs before I attended the Bootcamp so I had some understanding about the labs. Now I have been working with the Advanced Technologies workbook for my OSPF prep. I think OSPF is [...]]]></description>

If you are working on OSPF then you MUST know the different network types. I have been fortunate enough to be working with OSPF for sometime now so wanted to take some time and discuss all the Network types in OSPF.
Broadcast:

Default on Ethernet
Hello interval 10 seconds
Dead Interval 40 seconds
DR/BDR election
Updates are sent as multicast
Next hop  [...]]]></description>

I was working through Narbik's OSPF labs and ran across a few notes that I took in the class. I believe way too many network engineers get stuck when it comes to LSA types and Narbik did a great job teaching us the concepts. Here is a nice visio I did to capture the concepts! [...]]]></description>

I was not able to finish all the Frame-relay labs last night so I am already behind. I think I will dedicate my Saturday &#38; Sunday for all the leftovers. Today we covered OSPF and EIGRP with 40% lecture and 60% hands-on labs. Narbik started off with OSPF lecture and covered every single thing about [...]]]></description>

"Lab 9 - Limiting the number of OSPF redistributed routes" goes over limiting the number of redistributed routes in OSPF. Never did this before in my life and this is an interesting option. When I see something for the first time, I want to make sure I read the documentation on it. So let's see [...]]]></description>

"Lab 8 - Redirecting traffic in OSPF" goes over how to define which path a router will use to get to a path if two equal cost paths are available. We can use the "max-metric" command under the router process.
Router(config-router)#max-metric router-lsa
This command will cause a router to originate LSAs with a maximum metric of 0xffff [...]]]></description>

"Lab 7 - Filtering routes in OSPF"
One thing I have definitely learnt while working on these OSPF labs is that by default OSPF advertises loopbacks as /32 and in order for us to advertise the correct mask, we have to use ospf network type point-to-point.
router(config)#interface loopback0
router(config-if)#ip ospf network point-to-point
Filtering Outgoing LSAs
By default all outgoing LSAs [...]]]></description>
